Mk4 2021 Jazz Brake failure

[CB72]

There have also been reports of this on the Jazz Facebook page. Sounds like the dealers need to keep one of these items (brake simulation unit) in stock. Another thing to add to my startup anxiety list

The problem seems not to be limited to Jazzes:

What was wrong with the decades old, reliable, servo assisted hydraulic brakes

These fancy systems seem unreliable to me

I can recall plenty of diy articles etc about  repairing old type servos and braking systems.  Less complex maybe  but  not infallible.

Looking at the various threads on this site it looks like CRV owners have the same problems as Jazz owners which leads me to think that it includes the whole range of Hondas too.

I remember when cars had a mechanical connection between the brakes and your foot,  some just had a cable which would break on occasion. Didn't make them anymore reliable but maybe a bit cheaper to repair and lot of repairs and servicing you could do yourself.

Oh yes, pre-stretched cables

Stopping distances measured in miles

[Jazzik]

Maybe the solution?

My lhd Beetle had rod brakes hopeless went to scrap yard got flexy hoses if VW van + new brake line and fitted then splashed out in 4 used Michelin X tyres Ace result.
Cist will be driving factory on recent Honda systems let alone where made.

Its best not to get paranoid about it.  No car maker is completely immune from things going wrong  . And the fact it takes a while  to diagnose and obtain the parts  is in some ways a positive.  Better that than them knowing instantly and having the part in stock because it regularly fails.   But not much consolation if it happens to you .       Cars are getting increasingly complex but they are better. 

Also when looking at forums  for any make of car you have to allow for the fact people tend to post about any problems  or an aspect they dislike.  "Its  complicated" or   "a bigger car would have suited me better"  etc  . Fewer post  to say  "'Nothing has happened  and I love the car" But  reading between the lines I get the distinct impression most mk4 owners are very satisfied  with it  .

Fewer post  to say  "'Nothing has happened  and I love the car".

Okay, here's one: Nothing has happened  and I love the car! (except for that non-height adjustable passenger seat).

In case you are wondering what the purpose of a "brake feel simulator" is and how it works, I've found this presentation:

It is an older work from 2008 outlining the then popular hybrid braking systems of Honda, Toyota and Ford.
I think that most of it still applies (if not even more complex) to today's vehicules.

Short: There is more to a hybrid braking system than meets the eye!

Thanks. It's even more complicated than I thought.

Improving efficiency adds complexity.
